OTTAWA, Canada -- Canada's capital city is seeking bids for a company to operate "small" vending machines in city recreational sites, but gum will be forbidden, according to the Ottawa Sun.

The machines would be installed in up to 38 arenas and other recreation complexes to help generate revenue for the city. Ottawa's request for proposal specifies that the machines could vend candy, healthy snacks, "trinkets" and hockey sports cards.

A spokesperson for the city's parks and recreation department told the Ottawa Sun that the decision to exclude gum from machines in recreational facilities is an effort to reduce operational costs related to cleaning up discarded chewed gum. Also banned from vending machines are products containing peanuts and tree nuts.

The city also specified that it does not want more than half of machines at a single facility to dispense sugary treats.
